A girl asks her boyfriend to come over on Thanksgiving
and have dinner with her parents. Since this is such a
big event, the girl tells her boyfriend that after dinner,
she would like to go out and make love for the first time.
Obviously, the boy is ecstatic, but he has never had
sex before either, so he takes a trip to the
pharmacist to get some condoms. The pharmacist helps
the boy for about an hour, telling him everything
there is to know about condoms and sex.

At the register, the pharmacist asks the boy how many
condoms he'd like to buy, a 3-pack, 10-pack, or
family pack. The boy insists on the family pack
because he thinks he will be rather busy, it being
his first time and all.

That night, the boy shows up at the girl's parents
house and meets his girlfriend at the door. "Oh, I'm
so excited for you to meet my parents, come on in!"
The boy goes inside and is taken to the dinner table
where the girl's parents are seated. The boy quickly
offers to say grace and bows his head.
A minute passes, and the boy is still deep in prayer,
with his head down. 10 minutes pass, and the boy is
still deep in prayer. Finally, after 20 minutes of
praying, the girlfriend leans over and whispers to the
boyfriend, "I had no idea you were this religious."

The boy turns and whispers back,
"I had no idea your father was a pharmacist"
